misternice
Hi,theres nothing at all.the plug is all the way in,the tubes are seated properly,nothing on the screen.I may have to get a specialist onto it.
Looking back,on amps and pre amps,a few people have had a bit of a issue with the power side of things.It looks like a specialist will be able to fix it easy enough.Just a inconvienience
